ABSTRACT:
A self-contained, programmable temperature sensor is positioned within a suitable pressure housing affixed to a borehole tool to record and store temperature data at predetermined times during operations of the borehole tool in a borehole penetrating a subsurface formation. The depth of the temperature sensor within the borehole corresponding to each temperature reading is recorded. After the borehole tool is removed from the borehole, the temperature sensor is removed from the pressure housing and the stored temperature data is retrieved for use in producing a record of borehole temperature versus depth within the borehole at the programmed times.
